ZDNET’s key takeaways

• Samsung unveils a Privacy Display filter at Unpacked.
• The filter protects screens from prying eyes and can be turned off as needed.
• The Galaxy S26 Ultra is the only model so far to feature this innovation.

Overview

Most of the updates to the Galaxy S26 series announced at Samsung Unpacked were incremental—no major camera upgrades, no ultra‑powerful processor, and no groundbreaking AI features. The standout was the Privacy Display feature on the S26 Ultra, which could be the most significant smartphone innovation in years.

The Privacy Display lets you read the screen clearly when looking straight at it, while preventing nearby onlookers from seeing the content. You can disable it at any time to share what’s on the screen.

I’ve been a fan of privacy screen filters since the BlackBerry days in the early 2000s. Even now, they keep people on buses, trains, or planes from peering at my phone. However, they become a nuisance when I want to show my husband a reel or let my kids watch a backyard fox video.

Privacy Display’s best trick

The Samsung S26 Ultra’s Privacy Display is outstanding because it can be toggled on or off at any moment, letting you protect or share information as you wish.

You can even configure the feature for specific apps, so the Privacy Display only activates when you open a particular app or receive a notification from it. If a notification comes from an app on the Privacy Display list, only that notification is shaded when viewed from the side.

Samsung describes the feature as a way to control when you share your screen, not what you keep private. To make this possible, Samsung created the Black Matrix, a technology that narrows the light path emitted by each pixel on the S26 Ultra’s display.

The screen uses narrow and wide pixels:

• Narrow pixels act as the primary light source when Privacy Display is on. They have rings that make them visible only from the front.
• Wide pixels illuminate the screen from all angles and are used when Privacy Display is off.

If the technology works as Samsung promises, Privacy Display could become the new standard for phone manufacturers. For the rest of us who don’t have an S26 Ultra, we’ll continue using traditional privacy filters—smoothing out bubbles, cleaning dust particles, and tilting the screen to hide content from prying eyes.
